Try to reinstall "affy".

{I'm answering because the expert here is probably not yet at
 work ..}

All packages using S4 methods/classes are installed as
``binary'', and the problem could be that the internal metadata
representation of these things was extended changed from 1.5.x to 1.6.

This would mean you should probably re-install most bioconductor
packages since most of these rely on the modern methods.
